LASER MACHINES 3
1.2 LASER BEAM PROPORTIONAL TO AXIS FEEDRATE
In order to work with this feature, machine parameter “P619(3)” must be set to "1".
It is also necessary to adjust the axis servo drives so their maximum desired feedrates
(G00) are obtained with ±9.5 V.
When this feature is selected, the CNC will provide an analog "S" voltage (pins 36
and 37 connector I/O1) proportional to the actual (real) feedrate of the axes.
The CNC uses the "S analog" output to control the intensity of the laser beam;
therefore, the spindle parameters must be set accordingly.
Spindle machine parameters “P601(3)” and “P601(2)” must be set to "0" for the
analog output range to be ±10 V.
To get a unipolar analog voltage, set spindle machine parameter “P610(4)” to "1".
The sign of this unipolar analog output will be determined by spindle machine
parameter “P601(4)”.
The machine parameters related to spindle speed range (P7, P8, P9, P10) are set in
rpm. Therefore, whenever an "S" value is programmed, it will be indicated in rpm
and the CNC will provide the corresponding analog voltage depending on the speed
range it corresponds to the programmed "S" value.
The programming format used by the CNC for using this feature is as follows:
N4 G1 X±4.3 Y±4.3 F5.5 S4.4 M3/M4
The figure located between the "S" and the "." indicates the minimum analog value
(rpm) provided by the CNC and the figure after the "." indicates the analog (rpm)
corresponding to the programmed feedrate F5.5.
If there is no axis movement, the CNC will provide the programmed minimum S.
Otherwise, the CNC will supply the analog voltage corresponding to the actual (real)
axis feedrate.
In rapid positioning moves (G00), the CNC will output the programmed minimum S.
